The word ‘posture’ is quite misleading because its meaning is widely misunderstood.
Posture actually refers to the way in which a person is stood or moves.
The onus is upon the nature of their action, rather than a shape.

Thought tends to create fixed structures in the mind, which can make dynamic entities seem to be static.

(Will Keepin)

'13 powers', '13 principles', '13 patterns' or '13 ways' would be a more accurate description.

These are the 6 balanced pairs:

1. Hands & feet
2. Elbows & knees
3. Hips & shoulders
4. Back of head & coccyx
5. CV1 & crown
6. Buttocks & armpits

They are sometimes referred to as the '6 harmonies'.

Taoism is quite clear when it comes to mastery.
You must address your own concerns before attempting to control or manipulate other things.
Scholars of the tao question the very notion of mastery.

Neigong is ‘internal work’; a unique process of moving the whole body as one unit.
Rather than rely on tensed muscles, neigong teaches the student to remain physically relaxed and composed at all times, and move every body part together.
This is not as easy as it sounds.

Everything is changed by neigong. Every qigong exercise, form posture and movement is altered.
The body literally re-grows from the inside out.

Sifu Waller had a kind of internal arts open-house in the late 80's/early 90's, with students from all kinds of martial arts calling at his house. He met them at work, in classes, in bookshops, at workshops. They came and they trained. Shaun Ullah converted his living room into a dojo of-sorts, complete with wallbag, heavy bag and weaponry. This was a time of great sharing and discovery, with Sifu Waller at the centre yet taking no credit.

Muscles serve two main functions:

1. They help to hold the skeleton upright
2. They move the bones

If you encounter resistance but continue to push against growing pressure, which of these functions is being served?

Peter Southwood's main baguazhang influence is a man called Wang Shujin.

A kung fu student needs to have good character. They are held to a higher standard than other people.

Courtesy, manners, politeness and honesty are standard. Moral conduct and restraint are also expected.
It is important to take responsibility for what you are learning and show consideration to others who are less fortunate than you.

These may sound like old fashioned values but the martial arts tradition is an ancient one; and its values have proven their worth over the centuries.

Right conduct, courage, benevolence, respect, honour and self discipline are all a given in our classes.

Increased effectiveness is produced by gravity and heaviness in the striking limb, rather than pushing harder or striking faster.

Spontaneity is the key to fa jing. 

A tense body - with habitual holding patterns - will not provide an adequate conduit for kinetic energy to pass through.
If you can feel your own body moving, you are too tense. You should feel only the movement itself.

A free body is capable of striking instantly and spontaneously.

Fa jing looks fast but it is not a matter of speed. It is loose and sudden, not fast.
By relaxing the muscles and joints fully, the body is capable of spontaneous movement.
This is what makes fa jing seem fast - no preparation, no tensing-up beforehand.
Instant energy release.

The more advanced application of shuai jiao is abrupt and damaging.
The aim is to take the skills and reduce the time it takes to employ them.

Ultimately, it is is all about spontaneity.

There is nothing mystical or unscientific about 'fa jing'.
Despite the exotic Chinese name, it is simply a question of body mechanics, gravity, distance and timing.

It will not develop overnight but the seeds should emerge as the belts darken in colour, grow during the black belt level and flourish within the advanced syllabus.
